Right clay for Blossfeldia Liliputana?

[Avoniafanatic]

Hi Everyone!

I've decided to try my hand at growing Blossfeldia Liliputana from seeds. Anyone know the best type of clay to use to germinate? As I understand, equal parts sand and sifted, powdered clay are best, but im not sure where to get my hands on the right kind of clay

Thanks!

First of all, it would be helpful to know where you live, so please do this:

Also, you might want to post your inquiry again over in the Grown From Seed forum.

Where does that clay mixture come from? Is somebody trying to replicate habitat soils? If so they seldom work in pot culture. I would have thought normal seed raising methods would work for any dust like seeded cacti, they just take much longer than cacti from larger seeds?

Searching YouTube, is this video where your clay/sand idea came from? Afraid the sound is a bit "Donald Duck".

SuccSeed gives their method here. The "Baggie method" is a modern version of the "Fleischer Method" since it simply uses zip top plastic bags instead of sealed top glass jars. Both are actually forms of the old "Wardian Case" or "Terrarium" idea for providing a closed self sustaining atmosphere for plants or seeds.

Basically a "Wardian Case" and later "Terrarium" are a way of growing plants in a sterile self sustaining environment which was extended to seed raising in miniature form using glass jars with a sealable lid and alternatively just using zip top plastic bags
